[0029]
FIG. 2 shows the configuration of the multiple radio apparatuses 20a and 20b. Since the configurations of the multiplex radio apparatuses 20a and 20b are substantially the same, only the configuration of one of the multiplex radio apparatuses 20a is shown in FIG.
[0030]
The multiplex radio apparatus 20a includes a transmission unit 42, a reception unit 44, a transmission / reception sharing switching unit 46, a control unit 48, a power supply unit 50, a temperature sensor 51, a TFT (thin film transistor) liquid crystal display device (LCD) 60, and the LCD 60 A screen controller (screen control means) 62 for controlling screen display is provided.

It has a function to perform. That is, this single board can be shared with other multiplex radio apparatuses 20a and 20b, and can automatically display an alarm or the like according to the specifications of the mounted multiplex radio apparatuses 20a and 20b.

Of course, as the temperature sensor, a temperature sensor for measuring the temperature in the room where the multiplex radio apparatus 20a is installed can be installed separately from the temperature sensor 51 for measuring the temperature in the apparatus.
[0035]
Further, the power supply unit 50 is configured to supply power to the transmission unit 42, the reception unit 44, the transmission / reception sharing switching unit 46, the screen controller 62, the LCD 60, the temperature sensor 51, the modem 64, and the control unit 48. In FIG. 2, the power supply line is omitted.
[0036]
The control unit 48 configured by a microcomputer performs processing for controlling the transmission unit 42, the reception unit 44, the transmission / reception sharing switching unit 46, and the power supply unit 50, and the other multiple radio apparatus 20b and the terminal station apparatuses 22, 22 ′. A process of transmitting data to and the like is performed, and further, a communication process with the outside is performed through the modem 64 and the exchange 28.
[0037]
The transmission unit 42 includes two transmitters (transmission means) 52a and 52b, the reception unit 44 includes two receivers (reception means) 54a and 54b, and the power supply unit 50 includes two power supplies. (Power supply means) 56a and 56b are provided.
[0038]
Each of these transmitters 52a, 52b, receivers 54a, 54b, and power sources 56a, 56b is on standby for backup while the other is operating. That is, the transmitters 52a and 52b and the receivers 54a and 54b are selectively operated. Both power supply units 50 (power supplies 56a and 56b) are always in an operating state. However, when a failure occurs in one of the power supply units 50, the power supply unit 56a or 56b is backed up.
[0039]
When the control unit 48 detects that a failure has occurred in the transmitters 52a and 52b and the receivers 54a and 54b, the control unit 48 performs an operation / standby switching process so that the standby one is operated. Do. Although not shown in the figure, this switching processing switching unit is arranged in the transmission / reception shared switching unit (transmission system switching unit) 46 and the receiving unit 44, and is switched by a switching control signal from the control unit 48. It is done.
[0040]
Next, processing for detecting a failure in the transmission unit 42, the reception unit 44, the transmission / reception sharing switching unit 46, and the power supply unit 50 in the control unit 48 will be described.
[0041]
In addition, as a failure, transmission / reception power abnormalities in the transmitters 52a and 52b and the receivers 54a and 54b, such as a control malfunction in the transmission unit 42, the reception unit 44, the transmission / reception common switching unit 46, the power supply unit 50, etc., a circuit abnormality, a signal disconnection, etc. In addition to the local oscillator lock voltage abnormality, eye aperture ratio abnormality, cross polarization interference amount, and the like, the power supply voltage in the power supplies 56a and 56b (the power supply voltage includes the input side voltage, the stabilized voltage, etc.). Although an abnormality or the like is assumed, in the following description, the transmitters 52a and 52b (the ones in operation may be simply referred to as “transmitters 52”), paying attention to the transmission power that is a change with time. )) Will be described.
[0042]
First, the first and second methods for detecting a failure of the transmitter 52 will be described. In this case, the first method is a detection method for predicting the occurrence of a failure, and the second method is a method for detecting a failure that has already occurred.
[0043]
3 and 4 each show an example of a change characteristic with respect to time of the transmission power Wt [W] until failure occurs.
[0044]
As shown in FIG. 3, in the first method, the transmission power Wt of the transmitter 52 is monitored every predetermined period (for example, one day). The change in the transmission power Wt with respect to the time Ta [day (D)] is obtained as a polynomial represented by the approximate curve α from the monitored transmission power Wt values, for example, several tens of times (periods).
[0045]
In this case, the approximate curve α is determined in a range including a period after the last time when the transmission power Wt was measured (time Ta = 0 in FIG. 3). That is, a future change in the transmission power Wt can be predicted from the approximate curve α.
[0046]
In the example of FIG. 3, the transmission power Wt is stable at about 1 W at the time Ta = −10, but starts to gradually decrease before and after the time Ta = −5. At the time, it has dropped to 0.7W.
[0047]
The value of the transmission power Wt along the approximate curve α is below the failure definition level of 0.3 W at the time Ta = 3. That is, from this, it is estimated that the transmitter 52 will be in a failure state three days after the present time.
[0048]
As described above, when the value of the transmission power Wt gradually changes, it is possible to predict when the transmitter 52 will fail using the first method.
[0049]
Next, as shown in FIG. 4, in the second method, the transmission power Wt of the transmitter 52 is monitored every predetermined period (for example, several milliseconds). Then, it is monitored whether or not the monitored transmission power Wt is below the failure definition level (0.3 W).
[0050]
In the example of FIG. 4, the transmission power Wt is stable at about 1 W in the period before the time Tb [H] = − 2, but rapidly decreases from before and after the time Tb = −1. First, at time Tb = 0, it is 0.1 W, which is below the failure definition level. That is, it is determined that a failure has occurred in the transmitter 52 at the time Tb = 0.
[0051]
Thus, when the value of the transmission power Wt changes rapidly, the failure of the transmitter 52 can be detected using the second method.
[0052]
Note that the first method has been described with respect to the transmission power Wt as a monitor value. However, the received power, power supply voltage, eye opening ratio, local oscillator lock voltage, It is also possible to use monitor values such as the amount of cross polarization interference and temperature at the receiver.
[0053]
In the second method, a failure is detected based on alarm information detected in the case of a control malfunction, circuit abnormality, signal disconnection, temperature abnormality by the temperature sensor 51, etc. in addition to the monitor value indicating the change with time. You can also
[0054]
Next, the controller 48 uses the first and second techniques to detect failure of the transmitters 52a and 52b, the receivers 54a and 54b, and the power sources 56a and 56b (also simply referred to as the transmitter 52). This example will be described with reference to the flowchart of FIG.
[0055]
As described above, the first method is a detection method (failure occurrence prediction method) for predicting the occurrence of a failure, and the second method is a method for instantaneously detecting and determining a failure that has already occurred. (Instantaneous failure determination method). Therefore, in practice, the instantaneous failure determination method is executed by the control unit 48, which is a dedicated processor, so that the switching process is performed instantaneously. However, the failure occurrence prediction method is not instantaneous. Therefore, it is executed by the screen controller 62 which is a so-called one-board personal computer. In the following description, for convenience of understanding the present invention, the first method and the second method will be described simultaneously with reference to the flowchart shown in FIG.
[0056]
First, in step S11 (acquisition means), the control unit 48 captures transmission power Wt and the like (time-dependent change value) of the transmitter 52 and the like at intervals of, for example, several milliseconds.
[0057]
Then, in the subsequent step S12 (detection means), it is detected whether a failure has occurred in the transmitter 52 or the like using the second method. Specifically, it is determined whether or not the transmission power Wt or the like exceeds a predetermined failure definition level (see FIG. 4).
[0058]
If it is determined in step S12 that a failure has occurred in the transmitter 52 or the like (YES), the process proceeds to step S16. On the other hand, if it is determined that no failure has occurred (NO), the process proceeds to the next step S13.
[0059]
In step S13, it is determined whether or not the time point at which the transmission power Wt or the like has been taken in in step S11 is a time point to shift to the process in step S14 (that is, failure prediction process) described later. Specifically, it is determined whether the elapsed time from the time when the processes of steps S14 and S15 were performed last time has reached a predetermined time interval (for example, 24 hours).
[0060]
If it is determined in step S13 that the elapsed time has reached 24 hours (YES), the process proceeds to the next step S14. On the other hand, if it is determined that the elapsed time has not reached 24 hours (NO), the process returns to step S11.
[0061]
In step S14 (detection means), analysis processing such as transmission power Wt using the first method is performed. Specifically, an approximate curve α (see FIG. 3) such as the transmission power Wt with respect to time is obtained from the values of the transmission power Wt and the like obtained this time and in the past.
[0062]
Next, in step S15 (detection means), whether or not the value of the transmission power Wt and the like along the approximate curve α etc. exceeds the failure definition level within a predetermined period (for example, 3 days) (that is, within the predetermined period) Whether or not there is a risk of failure in the transmitter 52 or the like) (see FIG. 3).
[0063]
If it is predicted in step S15 that a failure may occur (YES), the process proceeds to step S16. On the other hand, when it is predicted that there is no possibility of failure (NO), the process returns to step S11.
[0064]
In step S16, the operation machine switching process is performed in the transmission unit 42 and the like in FIG. For example, when a failure occurs while the currently operating transmitter 52a is in operation (or the occurrence of a failure is predicted), transmission waiting from the transmitter (the currently operating means) 52a. Switching processing of the operating machine to the machine (standby means) 52b is performed.
[0065]
Needless to say, a combination of a plurality of operating machines currently operating and a single standby machine is also possible.
[0066]
In the subsequent step S17 (notification means), processing for notifying the content of the failure to the vendors 36a and 36b, the maintenance companies 38a and 38b, etc. via the Internet 14 is performed.
[0067]
FIG. 6 is a flowchart showing the subroutine processing in step S17.
[0068]
In this subroutine processing, first, in step S21, the content of the failure that has occurred in the transmitter 52 or the like is confirmed. In this case, the content of the failure includes information such as the device related to the failure, the cause of the failure, and the date and time when the failure occurred (or is expected to occur).
[0069]
Next, in step S22, a message in an Internet e-mail format is created based on the confirmed failure content. Note that the data acquired in step S11 described above, the data analyzed in step S14, and the like are attached to the message as an attached file.
[0070]
In the subsequent step S23, a message with data attachment is transmitted from the control unit 48 to the vendors 36a and 36b, the maintenance companies 38a and 38b, etc. all at once as an email. At this time, the same data attachment message is also sent to the administrator computer 32 provided in the local system 12A.
[0071]
Here, when the multiple radio apparatuses 20a and 20b are provided in the local system 12A provided with the exchange 28 for connection to the Internet 14, as shown in FIG. By the dial-up function provided in the unit 48, the data is sent from the multiplex radio apparatuses 20a, 20b to a predetermined mail server on the Internet 14 via the exchanges 28, 34.
[0072]
On the other hand, when the multiplex radio apparatuses 20a and 20b are provided in the local systems 12B, 12C, and 12D that do not include the exchange 28, the data attachment message of each of the multiplex radio apparatuses 20a and 20b is: These local systems 12B, 12C, 12D, etc. are sent to the local system 12A via the wireless digital information network formed by these local systems 12B, 12C, 12D, etc. and the local system 12A, and then from the local system 12A to the Internet 14 Sent to the side.
[0073]
In practice, the prediction determination processing according to the first method (failure occurrence prediction method) described above is performed in the local system 12A in which the exchange 28 exists, and the prediction determination processing is performed from the other local systems 12B to 12D. Only the acquired data related to is transmitted to the local system 12A.
[0074]
For example, a data attachment message from the local system 12C is sent from the local system 12C to the local system 12A via the local system 12B, and a prediction determination process is added by the local system 12A, and then data is attached to a mail server or the like. Sent as a message.
[0075]
In addition to the message sending process (or instead of this process), a process of automatically posting the same content as the message on the home page on the Internet 14 may be performed. Further, it may be notified to a notified person who is moving and carries a mobile phone or the like in a so-called mobile environment. In this way, information sharing among a plurality of parties can be easily realized.
[0076]
The vendors 36a, 36b, maintenance companies 38a, 38b, etc., who have received the message transmitted in step S23, confirm the contents of the data attachment message, decide the repair method, and repair the transmitter 52, etc. Do. In this case, by automatically interpreting the data attachment message and executing a program for searching for a repair method, the repair can be speeded up, and a serious failure such as a system failure can be prevented.
[0077]
In this case, since each multiplex radio apparatus 20a, 20b can be connected to the Internet 14, in addition to repairing directly on site, a method of correcting an operation program or the like through the Internet 14 (online correction method) Etc. can be adopted.
[0078]
It should be noted that failure prevention processing may be performed on the transmitter 52 and the like based on failure occurrence prediction.
[0079]
As described above, in the embodiment of the present invention, when a failure occurs in the transmitter 52 or the like, the e-mail including the information is directly sent to the vendors 36a and 36b or the maintenance company without going through the administrator. 38a, 38b, etc. For this reason, it is possible to promptly notify the occurrence of a failure. Further, even when a person in charge such as the vendors 36a and 36b and the maintenance companies 38a and 38b is absent or moving at the time of transmission of the electronic mail, the notification can be surely performed.
[0080]
Furthermore, it is possible to perform repair work more quickly by predicting the occurrence date and time of the failure from the monitor value such as the transmission power Wt and notifying the prediction result.
[0081]
Further, by using an e-mail or a homepage for the failure notification, it is possible to ensure the broadcastability of the information regarding the failure, and as a result, it is possible to perform repair work etc. quickly and efficiently.
[0082]
In this case, by sending an e-mail to a mail server or the like using a dial-up function, a communication cost can be reduced only when a failure occurs, thereby reducing communication costs.
[0083]
Messages from the local systems 12B, 12C, 12D, etc. that do not have the function of connecting to the Internet 14 are sent to the local system 12A having a function of connecting to the Internet 14 via the wireless digital information network. And sent to the Internet 14 side. For this reason, it is also possible to promptly transmit data attachment messages from the local systems 12B, 12C, 12D, etc. that do not have a function of connecting to the Internet 14.
[0084]
In addition, this monitor information can also be used for daily inspection work by periodically transmitting monitor information such as transmission power Wt by e-mail.
[0085]
